speaker cable upgrade for Inner sound ESL amp?


Hi everyone! I could really use some advice. I just purchased the Inner Sound ESL stereo amp and I have M-L Aerius I speakers. I am currently using MIT T2 Bi-Wire(8ft) speaker cables, which sound fine. However, I now need longer
cables(12ft). I am thinking I ought to take this opertunity to upgrade the speaker cables in the process. I would like to spend around $500 on used cables. Any suggestions for a synergistic match? My pre-amp is a C-J PFR. I am using MIT 330's for interconnects, however, I also have a couple pairs of Kimber Silver Streaks I can use.

Thanks to all of you in advance,

The speakerwire Inner Sound sells, work excellently well with the InnerSound amp you have and they are well within your price range. You can order direct, I think, through www.InnerSound.net. Cheers,
I second Detlof on this one, the Innersound cables are very good and cheap as well!
Have you used the Innersound ic's and speakers cables Rcprince and with what results? I'm currently using a biwire run of AP Oval 9's and wondering if the Innersound cables would better the AP's with my Magnepan 1.6's. Thanks.
